GAS cooLlNe. AND MIXING TOWER.

Specification of Letters Patent.

ratented April 2,1907.

Application iled August 23,1906. Serial No. 381,768.

To LZZ whom it may concer-n,.-

Be it known that I, JOHN T. HUTsoN, a citizen of the United States, residing at No. 158 Mills street, Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Gas Cooling and Mixing Towers, of which the following is a speciiication.

This inventionrelates to apparatus for condensing gases, and pertains especially to a gas cooling and mixing attachment for such apparatus.

The vobject of the invention is to provide novel and peculiar means for conveying gases from one to another of a series of condensing-chambers and for mixing and cooling the gases during their passage from one of such chambers to another preparatory for condensation.

A further object ofthe invention is to provide agas and air conveyer adapted to be interposed between and connected with a series of gas-condensing chambers, such conveyer comprising a tower provided with a central stationary air-shaft surrounded by gas-flue sections interposed by gas-mixing chambers and having spiral vanes.

A still further ob]- ect of the invention is to provide in a gas cooler and conveyer a central stationary air-shaft composed of a series of overlapping inverted funnels.

In gas apparatus to which this invention is specially adaptable a multitude of cooling and condensing chambers are employed. Between certain of such chambers it is common to introduce combination air and gas flues in communication with said chambers for cooling the gas. It is important that the gas should be retarded in its passage through the flues to increase cooling of the gas therein. As far as known to applicant the gas has been made to pass over and between frictionplates located in gas-iues or through a continuous spiral screw fixed to a stationary air shaft or pipe within the iiue. These devices have many disadvantages as compared with this invention. In such devices there is no provision in the air-shaft for introducing the air at various points in the air-shaft, so that a new supply of air may be drawn into the shaft, and there is no means for forming gasmixing chambers between the gas-iiues at intervals throughout the length of the tower.

It is therefore the purpose of this invention to furnish for use in condensing gasessuch as sulfurous gases, sulfur dioxid, and

sulfur trioxid-a tower in which gas is conducted through a series of spiral flues intervened by a series of gas-chambers, by which the latter are connected, and a central airshaft composed of sections adapted to take in air at various points throughout the length of the tower.

I/Vith these and various other objects, advantages, and improved results in view the invention consists in the novel construction and arrangement of parts, and essentially in atower having a series of inverted funnels constituting an air-shaft, a series of gas-mixing chambers surrounding the funnels and a series of gas-flues arranged in nests between the chambers and having a spiral gas-passage and a central gas-passage, both of which passages communicate with the said mixingchambers.

In the accompanying drawings forming part of this application, Figure l is a side elevation of part of a gas apparatus, showing the application of the invention. Fig. 2 is a vertical section of one of the cooling-towers embodying this invention. Fig. 3 is a section on the line :c Fig. 2. Fig. 4 is a section on the line y y, Fig. 2. Fig. 5 is a section on the line z a, Fig. 2. Fig. 6 is a detail vertical section of a modification, showing iiue connection without an air-shaft.

The same reference-numerals denote the same parts throughout the several views of the drawings.

For the purpose of illustration the invention is shown between and connected to two gas chambers or columns l; but the invention may be made to intervene any number of such columns as desired or as occasion may demand.

The bottom gas-receiving chamber 2 has a coupling 3 for connecting it to one of the columns l. An air-induction pipe 4 extends from the top of the chamber 2 and projects through the bottom thereof and through a iuting-pan 5, in which the bottom open end of the chamber 2 terminates. A like chamber 6, through which gas is exhausted, has a coupling 7, connecting it with the other column 1l and having an air-exhaust pipe 8 extending through a top pan 9 and projecting above the top of the chamber 6. The chambers 2 and 6 are connected by a series of gas-mixing chambers l() and a series of nests of gas-flues 11. The chambers 10 and iues 1l encircle an air-shaft, hereinafter particularly described. This constitutes the gas cooling IOO IIO

and mixing tower, further description of which in detail will now follow.

The chambers are annular or ringshaped, and the funnels 12 overlap in the central opening of the chamber-ring and are held by the chambers 10 in vertical position with the neck of one funnel projecting into the mouth of the adjacent funnel, said funnelnecks increasing in diameter from the bottom gas-chamber 2 to the top gas-chamber 6.

' These funnels and the pipes 4 and 8 constitute the air-shaft of the tower. The gasflues 11 are arranged to alternate in connecting the chambers 10 and the chambers 2 and 6-that is, the flues leading into certain of the chambers 1() are out of the vertical plane of the flues ,leading from the same chambers, so that the gas is diffused and retarded in its passage through the several chambers 10. Each fiue 11 of the severalnests of flues is provided with a central gas-tube 13, which telescopes the fiues, and a pair of spiral vanes 14, which span the space between the tubes and the fiues to give the gas a twisting motion and retard such part of it as passes through the spiral vanes while the other part of the gas has a more rapid passage through the tubes 13. The tower is supported from a suitable base 15 by standards 16 and brackets 17, bolted to annular flanges 18.

It will be observed that the funnels form a sectional open-air shaft through which the air heated by the gas is drawn away from the mixing-chambers and flues while a fresh supply of air is entering the mouth of the funnels-that is, a double diffusion of gases is made, one in the flues and the other in the mixing chambers, that the operation of diffusion retards vthe passage of the gases and keeps them moving around the air-shaft for cooling that an extra supply of airis drawn into the shaft at each and every gas-mixing chamber by the current of air through the air-pipes, and that the gases are alternately separated and mixed during their ascent through the tower, which delivers the gases to the condensing-columns at a very low temperature and such condition as to rendery them more susceptible to condensation.

Referring to the modification shown in Fig. 6 of the drawings, a single flue 19 is employed, having no air-shaft. The gas-tubes 20, gas-mixing chambers 22, and the spiral vanes 21 are of greater diameter. This flue is specially adapted for gas condensing plants comprising great (ten to fifteen) number of condensing chambers or columns 23, and by interposing this flue between said columns, or at least the first half of them, the gases are diffused and mixed in the fiues during passage from one to the other ofthe columns.

While the invention is described and shown for treating sulfurous gases and chemical gases, it is applicable in cooling, mixing,

and condensing gases of various other char'- acter, such as liquid air and gaseous vapor.

It is to be understood that suitable means may be employed to create lan air-current through the shaft, if necessary, and that the invention is not limited to any particular size and material, to the special number of parts, nor to the specific structure by which I have illustrated the same, but that the details may be extensively varied without departing from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas-Hue comprising a plurality of superposed gas-mixing chambers, a series of gas-pipes one within the other interposing and connecting the chambers, and spiral vanes between said pipes.

2. A gas-flue comprising a plurality of annular superposed gas-mixing chambers, a series of gas-pipes one within the other leading to the chambers, a series of gas-pipes one within the other leading from the chambers out of the vertical plane of said leading-in pipes, and a pair of spiral vanes between'the pair of pipes of each series.

3. A gas cooling 'and mixing tower comprising a funneled air-shaft, a plurality of superposed gas-mixing chambers encircling the shaft, and a nest 'of gas-pipes between and connecting said chambers.

4. A gas cooling and mixing tower comprising a funneled air-shaft, a plurality of superposed gas-mixing chambers encircling the shaft, a series of gas-pipes one within the other intervening and connecting the chambers, and a pair of spiral vanes within and spanning the space between the said pipes.

5. A gas cooling and mixing tower comprising induction and exhaust gas-chambers,

IOO

a plurality of superposed gas-mixing chamf 4bers interposed between the induction and exhaust chambers, a series of nests of gaspipes connecting the mixing-chambers and having spiral vanes therein, and an air-shaft extending through the nests of pipes and the mixing-chambers. 4

6. A gas cooling and mixing tower comprising induction and exhaust gas-chambers, a plurality of superposedgas-mixing chambers interposed between the induction and exhaust chambers, a series of nests of gaspipes connecting the mixing-chambers and having spiral vanes therein, and an air-shaft composed of a series of superposed inverted funnels overlapping each other and extending through the nests of pipes and the mixingchambers.

In testimony whereof I affix my signature in presence of two witnesses.
